The root of the issue was that my SmartSense Multi is firing multiple times (I have 2, and both are showing up with more events than they should) so I thought I’d replace the batteries. Well once I did that I wasn’t seeing anything in the mobile app react to it. So as I’ve had to do before I would delete the device and then re-add it, but tonight the app is not picking up the device at all.

My first reaction was to hit up the logs to see what’s happening and any time the SmartSense Multi changes state (acceleration, open/close) I get this line in my logs:

The UUID on the left also doesn’t change, so I know the hub can SEE the device, but it won’t add the thing…

It’s super frustrating because the Front Door multi still “works” (and by works I mean that it shows status, but fires multiple open/close events even where there is only one), but now I’m down a sensor.

The only messages you’re seeing in the Live Logging are coming from the a Hue (Connect) Device, which shouldn’t have anything to do with your SmartSense Multi (which, in fact, probably doesn’t send many Live Logging messages…). I’ve got Live Logging on and I’ll see how long it takes to get a message from a Smart Sense, to see it’s format. I’ve only ever noticed state change events (temperature, activity, open/close).

I definitely recommend contacting support@SmartThings.com as they will be able to recommend some steps and check the logs and device data in more detail to see if there’s some virtual wires crossed.

As a wild guess, there is a slight chance database corruption that is mapping the Multi to the Hue: But I think that is pretty unlikely. Love to find out what happened though, and might still be able to help. Keep me posted?
